REFRIGERATOR-CAR.

Application tiled February 23, 1912.

To all whom t may concern.'

Be it known that I, FRED PATEE, a citizen of the United States, residingat Denver, in the county of Denver and State of Colorado, have inventedcertain new and useful Improvements in Befrigc 'ator-Cars, of which thefollowing is a specification,

This invention relates to improvements in refrigerator cars. The objectof this invention is to provide an economical construction for cars,more especially for those cars designed for use as refrigerator cars.Another object of this invention is to provide a car with athermallyinsulated chamber in which perishable freight, or particularly foodstuffs may be carried and maintained at a uniform temperature withoutthe dan ger of rotting by being exposed to a circulation of moist air.Other objects will be apparent from the specification and appendedclaims, and from the drawings, in which- Figure 1 is a transversesection of a car embodying my improved Construction.

Fig. 2 is a fragmentary, vertical longitudinal section, the car beingbroken in two places to indicate the arrangement of the exhaustventilators.

Fig. 3 is a transverse detail section showing the corner arrangement ofthe car.

Fig. 4 is a detail section along the line 41, 11 of Fig. 1.

Like numerals refer` to like elements throughout the drawings.

10 designates the siding forming the foundation of the ends and walls.This siding 10 is secured to the framework which is composed of thehorizontal frame members or beams l1 and the vertical frame members orbeams 11 running between the members 11.

Secured to the outside of the siding is the metal lathing 12, preferablyof the sort formed with the ribs 12. Vhen this lathing is secured to thesiding 10, as will be apparent, dead air spaces 13 are formed betweenthe rib portions 12 and the outer surface of the siding 10. Furthermore,this use of the ribbed lathing is advantageous in securing the outsidecoating 14, preferably of asbestos, as shown in the drawing.

The roof, as shown in Figs. 1 and 2, of the drawings, is similarlyconstructed to the walls, with the exception that an outer protectingsheet 15 of corrugated metal may be laid on and secured to the coatingof asbestes.

serial No. 679,460.

Interiorly of the siding 10 in the spaces between the side beams 11 and11 is placed a filler of thermally insulating material 16. For thisfiller I preferably use a composition of asbestos, ground cork andplaster of Paris, although plain asbestos may be used.

Upright metal I-beams 17 are arranged at spaced intervals in the sidesand ends of the car. Located at the bottom of the car and having theirends adjacent the lower extremities of the uprights 17 are the crossbeams 18. The uprights 17 have one flange secured by screw bolts orother means to the inner surfaces of the frame members 11 and 11. Thecross beams 18 may be secured at their extremities to the side beams 17by rivets or other means, as indicated in the drawings.

Carried by the side beams 17 interiorly thereof are the inner walls 19comprising on the outside a layer of asbestos 20 and on the inside acorrugated sheet of metal 21 by which is carried the coating of asbestos20. An inner bottom 22 runs between the side walls 19 and is of the sameconstruction.

Some distance below the inside of the ear is arranged a ioor 23 formingthe roo-f of the packing chamber A which is inclosed by the side and endwalls 19, top 23 and bottom 22. The top 23 is composed of a sheet ofcorrugated metal 21 sloping slightly downward on each side to thecentral portion 24. The corrugations of the sloping portions 24E runtoward the central portion 211 which is formed with corrugations runninglongitudinally of the car, as shown in Fig. 1 of the drawings. Supportedupon the corrugations of the corrugated members 24 are the longitudinalstrips 25 of wood or other material. Below this member 211 and carriedthereby is an insulating layer of asbestos 2G forming the top surface ofthe packing chamber A. The top of the car and the floor 23 and the sideand end walls 19 together form an ice chamber B. Hatchways 26communicate therewith through which ice may be supplied.

In one Side of the ice chamber B I provide an opening 27 at the upperportion thereof, while at the other side of the ice chamber I provide anopening 28 adjacent the floor of said chamber, for a purpose to behereinafter described. It will be noticed that air spaces between theadjacent uprights 17 and cross beams 18 extend clear around the packingchamber. Through these air passa-ges or circuits a Vcurrent of cold airfrom the ice chamber is intended to travel. and the cross beams ll, llare coa-ted with a coating of Wateiproofed asbestos 30, as shovvn inFig. 4 of the draW- ings.Y This Will prevent absorption oi the moistureby the said coating and frame members. Ice supplied to the ice chamberB' will rest on the longitudinal strips25 and against Ithe longitudinalstripS5216- secu-red" to the 4sides and-endsofsaid--c-liainberto;
